In the history of mathematics, 2026 may mark a pivotal turning point. Over the past few months, the rapid development of artificial intelligence has shifted the focus from whether researchers will use it, to how they will collaborate with it. Emmanuel Breuillard, a professor of pure mathematics at the University of Oxford, suggests that the Fields Medal—often considered the highest honor in mathematics—might soon become obsolete. He questions how one can determine what part of a mathematical discovery is due to a person and what is due to a machine. As AI becomes more integrated into research, the traditional ways of recognizing individual achievement may no longer be feasible. This transformation extends beyond awards. The entire research ecosystem—ranging from intellectual property rights and academic publications to the evaluation of researchers and the training of students—could undergo a profound shift. For the first time in over two millennia, researchers have a powerful new tool: artificial intelligence. This tool acts like a "telescope" for the mind, enabling them to explore deeper and more complex problems than ever before. However, this metaphor is not purely abstract. The rapid growth of AI requires substantial resources, including more powerful computer chips, memory, data centers, and electricity. To address these energy demands, a field known as spintronics is gaining attention. Spintronics, which was pioneered in part by physicist Albert Fert, uses the spin of electrons—akin to tiny magnets—to store and process information. This technology could bring memory and computation closer together, potentially making certain computer architectures more energy-efficient. The concept of spin is relevant not only at the microscopic level but also in broader contexts, from the structure of our neurons to the magnetic fields of galaxies. The connection between these scientific advancements and real-world challenges is becoming increasingly clear. Recent heat waves in parts of Europe have provided a stark reminder of the tangible impacts of climate change. Eleni Myrivili, the global head of heat combat at the United Nations, stresses the urgency of preparing cities to withstand extreme temperatures. As science and technology advance, the bigger question is not just how far they will take us, but how we will adapt to live in the world they create.
